An informed source at EgyptAir stated that Flight no MS804, which departed Paris at 23:09 (CEST), heading to Cairo has disappeared from radar.

Aviation experts said the plane probably lost contact with ground radar above the Mediterranean Sea.

Aviation safety consultant Keith Mackey said “Apparently it was just short of Egyptian airspace, so it was likely over the Mediterranean, because the Greek airspace joins the Egyptian airspace around that area, So that is probably where they will be looking.”

“As day light comes, no doubt they will have airplanes and ships searching the area. If it crashed, it should not take long to find it in that area.”

“When a plane disappears suddenly like this you certainly cannot rule out terrorism or an explosion onboard the aircraft,” Mackey said.

Air Safety CrisisThis is not the first air-safety crisis Egypt has faced recently. In March, a domestic Egypt Air flight was hijacked and forced to land in Cyprus.

On October 31 last year, Russia-bound Metrojet Flight 9268, operated by Russian airline Kogalymavia, crashed in the Sinai Peninsula in Egypt, killing all 224 people on board.
